Abstract

The invention relates to a circuit arrangement for a photovoltaic inverter (1), said arrangement comprising two bus lines (8, 9), input terminals (6) for connecting at least one photovoltaic generator (7) to the bus lines (8, 9), one or more DC to AC converter(s) (10) connected to the bus lines (8, 9), a respective circuit-breaker (11) between each DC to AC converter (10) and the bus lines (8, 9) and a number of short-circuit paths (16 to 18) for short-circuiting a voltage present between the bus lines (8, 9), a short-circuit switch (19) being arranged in each path. In said arrangement, at least one (18) of the short-circuit paths between the bus lines (8, 9) runs in front of all circuit-breakers (11) and the short-circuit switch (19) in the at least one short-circuit path (18) between the bus lines (8, 9) is connected in series to a safety fuse (20).
